New clinical protocol after general surgery cuts opioid prescribing in half

Recognizing the role that opioid prescribing plays in the national opioid crisis, a team of researchers at Lawson and Western University have developed a new clinical protocol called STOP Narcotics. The protocol includes a combination of patient and health care provider education and an emphasis on non-opioid pain control. The study found that they were able to reduce the overall amount of opioids being prescribed after general surgery by 50 per cent while still adequately treating a patient’s post-operative pain. Read more.

Probiotics for respiratory tract infections could save Canada nearly $100 million a year

A recent study suggests the use of probiotics to prevent respiratory tract infections in Canada could result in nearly $100 million per year in savings. There is growing evidence that probiotics can reduce the risk of respiratory tract infections and lower their frequency, as well as reduce the duration of an infection, antibiotic use and absences from work. Replicating a research model used in France, researchers examined the potential clinical and economic impacts in Canada. Read more.

Blood test can predict optimal treatment for advanced prostate cancer, study finds

An international collaborative study between Lawson, Memorial Sloan Kettering Cancer Center, the Royal Marsden and Epic Sciences is one of the first to demonstrate that a blood test can predict how patients with advanced prostate cancer will respond to specific treatments, leading to improved survival. The study used a liquid biopsy test that examines circulating tumour cells (CTCs) in blood samples from patients with advanced prostate cancer who are deciding whether to switch from hormone-targeting therapy to chemotherapy.

Machine learning could predict medication response in patients with complex mood disorders

Mood disorders like major depressive disorder (MDD) and bipolar disorder are often complex and hard to diagnose, especially among youth when the illness is just evolving. This can make decisions about medication difficult. In a collaborative study by Lawson, The Mind Research Network and Brainnetome Center, researchers have developed an artificial intelligence (AI) algorithm that analyzes brain scans to better classify illness in patients with a complex mood disorder and help predict their response to medication.

Synthetic surfactant could ease breathing for patients with lung disease and injury

Human lungs are coated with a substance called surfactant which allows us to breathe easily. When lung surfactant is missing or depleted, which can happen with premature birth or lung injury, breathing becomes difficult. In a collaborative study between Lawson and Stanford University, scientists have developed and tested a new synthetic surfactant that could lead to improved treatments for lung disease and injury.

Family environment influences emotional well-being of children with epilepsy

Children with epilepsy have a higher risk of developing emotional and behavioural disorders, including depression, anxiety and poor self-esteem, yet it has been difficult for researchers to pinpoint why this occurs. Researchers at Children’s Health Research Institute, a Lawson program, have found that family environment influences the relationship between clinical characteristics of epilepsy at diagnosis and children’s emotional well-being two years later.

How the brain is folded provides researchers with an accurate marker to predict psychosis in high-risk patients

By using images of the brain to look at how its outer surface is folded on itself, researchers can predict which high-risk patients will develop psychosis with more than 80 per cent accuracy.  Before now, there has been no way to examine young people before they become ill to reliably identify who will develop acute psychosis and who will not.

High-dose radiation can improve survival in cancer patients once thought incurable

Cancer that spreads from an original tumour to other parts of the body is generally considered incurable. In an international study led by Lawson, researchers challenged this idea by showing that high-dose radiation can improve survival in patients with cancer that has spread to five or less sites. The study called SABR-COMET was the first randomized phase II clinical trial of its kind. Read more.

Thanks to decades of work by dedicated researchers like London, Ont.-based Dr. Paul Adams, haemochromatosis has become much easier to diagnose, though many people are still unaware of the genetic condition. And while treatment options are effective, they are limited, according to a new review published in The Lancet.

In Canada and the United States, one in 227 people have haemochromatosis, making it more common than cystic fibrosis. However, the U.K. Biobank Project, a large-scale biomedical database and research resource, found that only 12 per cent of people who have the condition actually know they have it.

Dr. Adams, a Scientist at Lawson Health Research Institute and Professor at Western University’s Schulich School of Medicine & Dentistry, explains, “The most common genetic test done in Canada and the U.S. is the best way to make the diagnosis, but you have to think of the condition and the doctor has to know that there is a genetic test available. So those two steps are some of our stumbling blocks.”

In Ontario, testing and diagnosis often comes only after some other issue arises, “One day someone stumbles on the fact that there's a liver abnormality, or the patient is complaining of fatigue and the doctor orders blood tests, thinking blood iron is going to be low,” Dr. Adams explains. “And then it turns out to be very high.” 

Most common in people of Northern European ancestry, haemochromatosis results in excess iron in the body and includes symptoms such as fatigue and arthritis pain, and can lead to serious complications like cirrhosis of the liver, liver cancer and death.

Starting in January 2000, Dr. Adams conducted a multi-year study involving 20,000 London, Ont. residents that helped change how haemochromatosis is diagnosed – moving from testing iron levels to genetic testing. With iron levels affected by alcohol consumption, obesity, inflammation and some types of cancer, the previous measure led to many false positive tests. 

But knowing when genetic testing should be done remains a challenge. The underdiagnosis and lack of awareness also remain an issue when it comes to more serious complications.

“If this is diagnosed early, like as a young adult, then this can be treated and those complications won’t develop,” Dr. Adams says. “If you donate blood, treatment is very similar to that procedure and it's tolerated extremely well in most. People who have a lot of excess iron will have this blood taken once a week until their iron levels come down.” 

He hopes this new publication will lead to better diagnosis and treatment, and sees a future in emerging biological therapies.

Dr. Adams continues to be involved in global research, including work with the U.K. Biobank Project on genomic testing, and is investigating partnerships to develop future gene editing treatment.
